  • Does the trick, and easy Install
Model: BI-2.5
Perfectly solved our need to get instant hit water in our high 2nd story bathroom, plus we used the included T-valve to easily split the line and feed a hot water bidet nearby. The water gets PIPING hot on the highest setting so we found that the middle setting is about right. The hot water only lasts for maybe 45-60 seconds at a time but that's enough for bathroom and bidet use (maybe not a kitchen sink). Very install install, although the instructions were quite vague. I'm a total plumbing novice but I figured it out. Maybe not the absolute best of this type of unit but it seems to get the job done! ... show more

  • Under the sink small unit solved the cold water problem
Model: BI-2.5
I ordered this small unit to put under the sink as a inline additional water heater to solve the cold water problem which caused by too long pipe from my main water heater to the faucet. It works perfectly for this purpose. The installation is simple and just follow the instructions, I connect my hot water pipe to the blue inlet, I got hot water immediately, after the reservoir 2.5G hot water runout, my house hot water coming in just right time after heat up all the long pipes. ... show more

  • Works fine at first.
Model: BI-2.5
This is a nifty little heater and it worked great at first. It was very easy to install and it provided fast, hot water as expected. However it began leaking at the top of the pressure release valve, and when I looked into the issue, it turned out the gasket on my hose was bad. That wasn't a big deal, but as I was tightening the new hose on to the pressure valve, the brass snapped at the pipe threads. I've never seen a hand-wrenched brass fitting break in my own hands like that before, and the the valve design appears proprietary so not easy to find a replacement. So, in summary, it's a good little heater, but the hardware is junk. Update: I replaced everything sealing every leak on top. Now it is leaking from the bottom. This product is garbage. ... show more

  • Great working product
Model: BI-2.5
The product works great! The water is so hot it's almost boiling from the tap with the setting my husband put it on. I would have given a 5 star rating but the shipping time was a full blown joke! It only lasted for a short time as the water where I live is full of deposits. It messed up the heating element 😪 . Trying to get a replacement was a joke because they told us they would reimburse if we bought another one. They wound up crediting the order. ... show more

  • Instant hot water from faucet in cold winter
Model: BI-2.5
I purchased this electric water heater to install under the sink to provide instant hot water because it takes a while for hot water to come out of the faucet for current tankless water heater. It came with all the necessary parts, including tee valve, hoses, pressure release valve, mounting kits. The 2.5Gallon size is small enough to fit under my sink. It is a must in the cold winter. ... show more

  • A small fix could get it 5 stars...
Model: BI-2.5
After using it for a good break in period, I am happy with it however if they included a reducer coupling, they probably have them in bulk for cheap, it would have saved me a 20 mile ride to buy one for $10 at the big box store and I likely would give this a 5. It heats well, but you have to train yourself to slow down a bit using it for the sink as the hot water will run out quickly if you dont. I would purchase again, but still add the coupler. ... show more
